URLLC stands for Ultra-Reliable Low Latency Communication. It’s one of the key use case categories defined for 5G networks by the 3rd Generation Partnership Project (3GPP) to meet the demands of new applications that require ultra-reliable, always available, and low latency connectivity services.
Key Features:
- Ultra-Reliability:
- URLLC is designed to provide extremely reliable communication, which is crucial for applications where data must be transmitted accurately and failure to do so could have serious consequences.
- Low Latency:
- It aims to achieve very low latency (as low as 1 millisecond), which is essential for applications that require real-time communication.
- High Availability:
- High availability ensures that the communication links are always active with almost no downtime.
- Predictable Communication:
- The consistency in the communication performance, in terms of both latency and reliability, is a key feature of URLLC.
- Real-Time Monitoring:
- URLLC can support real-time monitoring and control of applications.
Applications:
- Industrial Automation:
- URLLC is crucial for industrial applications where machinery and processes need to be precisely controlled in real-time to avoid accidents or production losses.
- Autonomous Vehicles:
- Real-time communication is vital for autonomous vehicles to navigate safely and interact with other vehicles and infrastructure.
- Healthcare:
- In healthcare, URLLC can support telemedicine, remote surgery, and other critical applications where real-time communication and reliability are essential.
- Smart Grids:
- URLLC can be used for controlling and monitoring electricity distribution in real-time to ensure reliable power supply.
- Public Safety:
- For emergency services and first responders, reliable and real-time communication can be life-saving.
